The tagline in the opening credits reads "E Pur Si Muove," which translates from Italian to "And still it moves," a phrase ascribed to Italian astronomer Galileo Galilei after his arrest, trial, and conviction for defending the Copernican heresy by the Catholic Church. According to legend, he would utter this after his prayers in quiet protest against the Church, although the stories of this occurring did not surface until a century after Galileo's death.
